Description

A kind of ventilation ventilated control system for cable duct
Technical field
The present invention relates to power domain, more specifically to a kind of ventilation ventilated control system for cable duct.
Background technology
Cable duct is to lay and replace the underground piping of electric power or telecommunication cable facility and by cabling facility Building enclosure, have the pipeline configurations form such as rectangle, circle, arch.
Cable duct layout pattern in power plant, substation is related with field device and orographic condition, but either indoor Or outside cable ditch generally all has following features:
First, cable duct is the raceway groove for having cover board, lays and must all open cover board when repairing cable, troublesome, inconvenient, ditch Siltation booty, ponding are inside also easy to, but because civil construction is simple, low cost, is often used in substation and middle-size and small-size power plant;
Second, switchyard area is generally provided with tour road, so that staff makes an inspection tour electrical equipment, many plant stands are led to Often cable channel cover plate is maked an inspection tour and operated trail as part;
Third, being equipped with cable bearer in cable duct, cable bearer is usually made by metal material, consolidates by welding or with screw It is scheduled on furrow bank, cable is held by stent, and a certain distance is remain with bottom of trench;Cable in cable duct would generally take fire prevention Measure including brushing fireproof coating, blocks isolation etc.;
